The word "symbols" itself doesn't have any particular "symbols of belief" associated with it. It's simply a word meaning "something that represents something else."
However, if you're asking about the stress in the word "symbols," then it's on the first syllable: SYM-bols. You can tell this because the stress is usually on the first syllable in two-syllable nouns.
